Germany Army have 2 work horses :
- G43 + Scope ( Pointer Quicker Fire works fine for cqc spam )
- Mp40
If you are going to buy both , you can put them on different soldiers . Buying many weapons on a single soldier is not a good idea .
Why you shouldn't waste your time with Stg44 :

If they don't fix AT rambos , it doesn't matter putting new armor to the game .Even Reto trying to fixing it with lazy&amateur ways , like " slowing down " movement .
All tanks are equal : put 2 x H3 and gg , doesn't matter which tank , only in different skins .

The game is based on this game -> http://joinsquad.com . Unreal engine and at this video he is on something like development tool .
For visual quality better look at here : http://postscriptumgame.com/screenshots

Actually , lazy&amateur Reto didn't implement any clan system to the game .
If they would implement clan system , clan stats on leaderboard would looks better and put some race to clans .
Any score from staged games shouldn't be on leaderboard , it shows nothing .
